Modelování porovitých stavebních materiálů metodou konečných prvků

Abstract

Porous materials are widely used in building industry at present. Due to their low bulk density they have very good thermal insulation properties. These materials has also some disadvantages. High porosity causes significant reduction of mechanical and durability parameters. Very adverse effect causes moisture which can penetrate to pore system. In the design and assesment of building structures it is neccesary to take account these circumstances. Standards for designing of building structures are very limited in this problematic. This diploma thesis is focused on modeling of mechanical behavior of porous materials. Numerical models with using of experimental data take into account effect of moisture on mechanical parameters. Some yield criterions for porous material from commercial, opens source and also custom software are used.
